Error in MSword 2007

Sir,

Whenever I direct click the MSword 2007 file, I receive message "There was problem in sending the command to Program" . I tried the solution given in the forum i.e Close the Word and Start > Run > winword.exe /r {ENTER} but I could not correct the problem. I uninstall the MSoffice 2007 and again install it but problem still persist. Can anyone give me solution for this.
Thanking you
